This PR fundamentally rewrites the Horizon transaction parser module to aggressively validate incoming transaction schemas before attempting to process them.
Using Zod, we now explicitly catch malformed schemas (like LP shares) and route them to dead-letter logs instead of allowing them to silently kill the SSE listener loop. This ensures that the merchant deposit pipeline remains totally unbroken even during network spam.
Closes #33.
